Hiya All,
I'm now in touch with Canon UK as I want to find out what this crud is & where it came from ( nothing to do with changing lenses ) I can't help feeling there is something ' Within ' that's causing this problem, it's obvious that whatever it is it's oily/sticky & as this occurred when the lens was already on there & had been for wks. then it's gota be internal surely. so we shall wait & see what Canon have to say for themselves eh.
Brian,
I just hit the auto fix, I've taken a few shots including some Landscape with the 17-70 & the crud is still as plain as the nose on ones face I'm now concerned that the clarity isn't so good things look a bit ' Misty ' so for my own piece of mind I want Canon to have a look see, I'm just so gutted
Allan,
He used swabs of some sort, it just seems strange that it won't come off as it obviously can be moved around, my fear is that is some mineral oil & it's coating the sensor & maybe scratching it, as I said above to Brian I've taken some shots & they look ' Misty ' which is most disconcerting & also hold up my theory that whatever it is, it is being spread rather than removed, I hear where you're coming from about the two spots but clean means clean
Gordon, that's very tempting
Thanks for all comments
Cheers for now
Mark
